Eric Dumazet says:

====================
tcp: receiver changes

Before accepting an incoming packet:

- Make sure to not accept a packet beyond advertized RWIN.
  If not, increment a new SNMP counter (LINUX_MIB_BEYOND_WINDOW)

- ooo packets should update rcv_mss and tp->scaling_ratio.

- Make sure to not accept packet beyond sk_rcvbuf limit.

This series includes three associated packetdrill tests.
